Specification of Letters Patent.

Patented Dec. 3, 1907.

Application filed June 30. 1906. Serial No. 324.228.

To all whom-z it may concern: i

Be t known that 1.. AUGUST VON PARSE resid en t of Augsburg. Germ any .have invented certain new and useful Improvements in Car Suspensions forMotor-Balloons, of which the following is a specification.

This invention relates to motor balloons and especially to motorballoon-suspensions its object being to provide a suspension of thiskind which would be very simple in construction and very efiicient inuse.

In the annexedydrawings: Figure 1 is a side elevation view of a balloonthe car of which issuspended according to the present invent-ion. Fig. 2is a front elevation of same.

The new suspension comprises the well i known. parallel pairs of cables1 and 2 which have the same length and rigidly connect the middle partof the balloon with the car,-

as well as t e oblique ropes 3 and 4-, which supports the projectingpoints of the balloon and pass at the car under gliding rollers 5 and 6.

When the car oscillates it follows circular courses at the ends of theropes 1 and 2 while sliding by means of the rollers 5 and 6 on thesliding ropes.

In order to prevent oi the axis of the balloon being deformed. by thesliding'ropes the dimensions of the ropes are calculated in 'such amanner that the circular motion of the points 7 and 8 coincides withinthe limits 9 and 10 of the motion of the car which are practically to beconsidered, with that part of the elliptical way which corresponds tothe motion of the slide ropes. The focuses oi the ellipsis are at 11 and12.

The advantages oi this suspension are the following:

l.-A long and rigid supporting framethe motor and the balloon any dangerof explosion is excluded.

4.The upwardly directed tilting moment of the low placed propeller screwis strongly diminished as under the pressure of the propeller screw thecar automatically advances and carries its center of gravity ahead.

5.-Owing to this advancing and following motion of the car the. pitchingmotions of the balloon produced by the variation of the speed areconsiderably reduced.

Consequently in spite of the low position of the car dynamic eiiects areobtained as it the car be suspended. very high i. e. at the height ofthe securing points 13 and 14 of the parallel ropes. i

The above describedcar suspension conse quently unites the advantages ofa low posi tion of the car with that of a highly positioned'center ofgravity of the car.

The arrangement may also be used as a rigid suspension if it is desiredto control the inclined position of the balloon by shifting the centerolf gravity of the car. In this case the car may be held in the desiredposition by the sliding ropes themselves, by connecting the latter witha roller 15 in such a manner that the rope is prevented from slipping onthe roller. The mechanical rotation of this roller produces the shiftingof the car.

Having now fully described my said invention what I claim and desire tosecure by Letters Patent is:

.1. In combination, a balloon, a car, flexible supporting ropesconnecting-the car with the balloon, and flexible guiding ropes securedto the balloon 'and slidably engaged with the car to permit movement ofthe same, the guiding ropes being so arranged with respect to thesupporting ropes and the two sets of ropes being so proportioned thatboth are maintained taut by the weight of the car in any posit on whichthe same may assume.

2. In combination, a balloon, a car; flexible supporting ropesconnecting the car with the balloon and permitting movement of the car,rollers for the car, and flexible guide ropes longitudinally disposedwith respect to the axis of the balloon. and connected therewith, saidropes passing beneath said rollers, said supporting and guide ropesbeing so proportioned and disposed with respect to each other that theWeight of the car maintains being so proportioned and so disposed withsaid ropes taut in any'position which it ma, respect to each other as todistribute the assume. p weight of the car equally thereon.
